I want to translate content using I guess it is called the "classic" editor. I just want a new blank page I can set my translated content freely (of course, I want the category, featured image to be copied from the original language). I have set up "Classic Translation Editor" for new translations as well as for "translations previously created using Classic Translation Editor". (Please see attached "settings").
Then, when I click to add a translation, I get a translation page where I have to define translations by "block" lets say. I have the original content on the left, and the translated content on the right. I am not sure it ny translators would like to have the screen divided on two columns. Please see attached image (translator).
Is it possible to just have a blank new page, where we can paste the translated content?
